The Collaborative for Leadership in ASI (CLASI) provides a Certificate Program in Ayres Sensory Integration® (ASI) reflecting the evolution of the body of knowledge that is now trademarked as Ayres Sensory Integration® to reflect the theoretical principles, assessment methods, and intervention strategies developed and pioneered by Dr. Ayres. The CLASI-CASI is an evidence-based program following in Dr. Ayres’s legacy of scholarship and a commitment to research.

CLASI’s Certificate in Ayres Sensory Integration (CASI) is an advanced training program that was initiated in 2016 to continue the legacy of excellence in education, research, and practice in the body of knowledge which was originated by Dr. A. Jean Ayres and which has been continued by other researchers, practitioners, and educators. This education program is produced according to the guidelines of the International Coalition of Education in Ayres Sensory Integration® and aligned with the Ayres 2020 Vision, promoting excellence in scholarship, assessment, and education in ASI.

The CLASI-CASI program includes 6 Modules, 30 contact hours each. Four (4) modules are offered via asynchronous virtual format, and two modules are offered onsite. 

CLASI modules include supplemental activities, assignments, and webinars, for a total of 180 hours. The modules are designed for therapists as a comprehensive and practical foundation of knowledge and skills in ASI theory, assessment, and intervention. The training builds competencies from research to practice, including administering and interpreting standardized, norm referenced tests . Following completion of the 6 modules and all assignments, participants receive the CLASI Certificate in Ayres Sensory Integration.

Module 1 – Open to all who wish to learn about ASI theory.

Module 2, 3, and 4 – Open to healthcare professionals with at least bachelor-level equivalent college/university degrees in occupational therapy, speech pathology, physical therapy, psychology, or medicine. Module 2 is a prerequisite to Module 3.

Module 5 – Open to all who wish to learn more about evidence-based manualized ASI Intervention. Module 4 & 5 are prerequisites to Module 6.

Module 6 – Open to Occupational Therapists (OT), Physical Therapists (PT), and Speech and Language Pathologists (SLP). 

CLASI-CASI Modules 1-5 are prerequisite to Module 6. Those with prior advanced training in ASI are welcome to enroll and update their knowledge. If you have advanced training in ASI, please contact your course host to confirm your eligibility.

Participants will receive a certificate of attendance to verify continuing education credit (approved by the American Occupational Therapy Association (AOTA) for each Module. However, the CLASI – CASI Certificate in Ayres Sensory Integration is restricted to occupational therapists, physical therapists, and speech and language pathologists

Certified Occupational Therapy Assistants (COTA) are welcome to join Modules 1, 5, and 6 with a letter of recommendation from a supervising occupational therapist.

Based on our work with Dr. Ayres, we believe that comprehensive assessment is a cornerstone to appropriate and effective intervention. 

The Sensory Integration and Praxis Tests (SIPT) were the gold standard for assessing sensory integration functions for many years. 

The Evaluation in Ayres Sensory Integration ©(EASI), designed for children aged 3 to 12 years and with international normative data from more than 80 countries, is now available for comprehensive assessment of sensory integration, in an inclusive and cost-effective manner. Standardized questionnaires, such as the Sensory Processing Measure, also continue to be an important aspect of comprehensive assessment in ASI. 

Therefore, the CLASI CASI includes instruction and mentored practice in the EASI and the SPM.

The CLASI CASI modules provide detailed training in the EASI and the SPM. Rather than providing a certification in any one set of tests, we strive to enhance an understanding of the core concepts of ASI, including the main areas that must be included in a comprehensive assessment.

Simply, CLASI's certificate encompasses the broad set of knowledge and skills that support therapy practice using Ayres Sensory Integration ®. The CLASI program emphasizes the importance of comprehensive assessment and provides training and mentored support so that therapists can feel competent to administer and score assessments in a valid, reliable and feasible manner and then inform their clinical reasoning to plan and implement effective intervention with fidelity to evidence-based principles.

To provide some historical background, the idea of "Certification" was the name for the certificate process originated by the Center for the Study of Sensory Integrative Dysfunction (CSSID), later known as Sensory Integration International (SII), 1976-2006. SIPT Certification was first offered after professionals received training in the Southern California Sensory Integration Tests (SCSIT), then later in SIPT.

From 1998-2016, the USC/WPS program offered the Certificate in Sensory Integration, which included training in administering and interpreting the SIPT. The certificate was in Sensory Integration and included the SIPT, but was explicitly not a certification series, rather a certificate program and not "SIPT Certification" since it focused on all aspects of the Sensory Integration frame of reference, theory, assessment and intervention.

Completion of the CLASI CASI program provides therapists the opportunity to obtain the Certificate in Ayres Sensory Integration ®, which in includes administering and interpreting the tests which assess the core constructs of ASI and evidence based ASI intervention with fidelity to the structure and process elements as defined in the literature.

A complete list of the courses and assignments required for receiving the CLASI CASI are available here.

Typically, once registered, online course content can be accessed for at least one year. It is our hope that these materials will be reviewed to support ongoing learning throughout the process. We recommend that participants complete the whole program, Including the onsite modules and assignments, within one year. Since life sometimes gets in the way of plans, the maximum amount of time allowed for completion of the program is five years.

We recommend taking the modules in order, but we realize there may be exceptions.

Module 1 (Ayres Sensory Integration Theory) – These asynchronous virtual lessons in ASI theory can be completed over time, and review of this information throughout the program is recommended. While it will be helpful to complete Module 1 prior to Module 2 & 3, it is not essential. However, it will be very difficult to fully synthesize the information in lessons Module 4 - 6 if Module 1 has not been completed.

Module 2 (Comprehensive Assessment in ASI) – The asynchronous virtual lessons in ASI assessment must be completed prior to Module 3 since this module provides essential information for administering and scoring a variety of assessment tools which will be only briefly reviewed and then practiced in Module 3.

Module 3 (Hands-on Comprehensive Assessment in ASI) – This onsite or synchronous virtual ASI hands-on course assessment information must be completed prior to Module 4. The tests which are learned and practiced will be used to evaluate children with valid and reliable results prior to interpreting those data.

Module 4 (Clinical Reasoning in ASI) – this asynchronous virtual module provides an analysis of the evidence supporting ASI clinical reasoning. Module 4 is needed prior to Module 6 because Participants will need to complete assignments that rely on the content in Module 4, in order to participate in Module 6.

Module 5 (Evidence-Based ASI Intervention Including Fidelity to Intervention) – These asynchronous virtual lessons for Module 5 provide an introduction to the evidence and principles of ASI intervention including the ASI fidelity measure. Module 5 provides the tools to evaluate whether there is sufficient adherence to ASI principles during a therapy session to be considered evidence-based ASI intervention. Like Module 4, Module 5 involves assignments that are required prior to participating in Module 6.

Module 6 (Evidence-Based ASI Intervention Hands-on Practice and Review) – This onsite or synchronous virtual module in ASI hands-on intervention is best completed once you have a firm foundation in theory, assessment, and principles of intervention.

Applying hours of training completed from another organization toward the CLASI CASI will be decided on a case-by-case basis. Consideration of the completed training in regard to the ICEASI standards and the length of time since the training was completed will determine whether or not it is possible to apply credit from another program.

Professionals who have completed other certification programs or have participated in advanced training in ASI in the past, may find enrollment in any of the CLASI modules beneficial as “refresher courses."

Each module will provide 30 hours of training, including the assignments, for a total of 180 hours for the program. CLASI is an approved provider of continuing education units (CEU) by the American Occupational Therapy Association. In the Philippine setting, this certification can be applied for self directed learning under PRC.

While we cannot evaluate or represent other programs, we are happy to describe ours. The CLASI program was developed by Zoe Mailloux, OTD, OTR/L, FAOTA and Susanne Smith Roley, OTD, OTR/L, FAOTA both of whom were students of Dr. A. Jean Ayres. They are committed to following her tradition of excellence and research in practice. Course materials are derived from Ayres’ original publications and subsequent research in basic and applied science related to sensation and the impact on human function. In addition, CLASI instructors are lecturers with in-depth knowledge in the areas of ASI, representing first- and second-generation students of Dr. Ayres. The instructors have national and international experience in presentations of information on ASI and expertise in ASI research, education, and practice.

CLASI is also a founding member of the International Council for Education (ICEASI) in Ayres Sensory Integration®, an organization which aims to provide global standards for education and training in ASI.

The ICEASI is a non-profit organization with the purpose of promoting the exchange of knowledge among member organizations, support research and provide global standards for education in ASI. 

ICEASI has developed a set of principles to guide the education of professionals to ensure that those who have completed training to the ICEASI standards will have the competencies required to ensure best practice with Ayres Sensory Integration®. 

ICEASI is developing “levels of competencies” to assist professionals to track their own professional development and to assist consumers and those who need to make referrals to locate appropriate resources.

To receive the final certificate, learners must document the completion of a comprehensive assessment of sensory integration applying the EASI with at least two typically developing children and analyze an assessment on at least one child who has been identified as having concerns. A checklist of items needed for learning, practicing, administering, and scoring the EASI are provided in the resources section of CLASI's assessment Modules (Modules 2 & 3).

Participants in the CLASI CASI who have access to SIPT materials and who wish to test children on the SIPT as part of the case requirements may do so. Therapists will be guided through the interpretation process with the tests they apply and through cases provided in the modules.
